[@isabellcardenas1309]

the BIGGEST thank you goes out to you sir!!! i’ve been struggling with this concept for days now & i just could not grasp it with what my teacher was giving. you explained everything so clearly & easy to understand!! thank you so much !

[@stepbystepscience]

You are very welcome, and thanks for the very nice comment.

You may find a comprehensive description in the refetences here on the physics of the networks. What is a resistor? How does current branch in a network of resistors? How does it "know" how much should flow in each branch? While some detail is given in science and engineering courses about conductors, insulators and semiconductors, resistance is described in several ways. Examples include i. The restriction to the flow of electrons. ii. The difficulty in moving electrical current through a conductor to which voltage is applied. iii. a circuit element which dissipates energy in the form of heat . More appropriate description for a resistor would be the property of a conductor which determines the current produced by a given difference of potential. This makes us remember that a resistor is a conductor first. And, there is reason to say that superconductive wires dont obey ohm's law. So all conductors are resistive, though not superconductors. Resistors are used in circuits to regulate the strengths of currents either by reducing the diameter of conductors or introducing more obstacles or lattice imperfections to reduce the strength of current. The current branches in a parallel network by an elaborate rearrangement of surface charge. For more details about resistance, how current branches in a parallel circuit and ohm's law consult the following videos, articles and books. What is current ? What is voltage ? A working definition for current in conductors like metal wires is "the start-stop motion of millions and millions of conduction band electrons everywhere within with a drift superimposed". In circuits, voltage is due to surface charges. Consider a simple circuit comprising a battery, two wires and a resistor. The e.m.f of the battery is due to separation of positive from negative charges which produces an e.m.f across its terminals and a pattern of electric field surrounding them, not exactly but like a dipole. An electric field is there in the wires and in the resistor; powerful electric field and uniform within the resistor, weak and uniform within the wires. The field is set up by a tiny amount of surface charge with a steep gradient on the resistor and not so steep a gradient on the wires. It is the electric field E created by the surface charges sourced from the battery, which produces a force causing the mobile electrons to acquire a drift velocity v = μE, where μ is the mobility which is a number representing the freedom of movement of the electron in the lattice. This results in a current density J = σE, where σ is the conductivity of the wire or material of resistor and E is the electric field in the wire if considering wire and is the field in the resistor when considering the resistor. The p.d. or voltage across the resistor is the integral of a constant powerful field along its length. The p.d. or voltage across the wires is the integral of a constant but weak field along its length. Voltage is entirely because of the surface charges. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism.

I like to say that when you are adding resistors in parallel, the important thing to remember is that you are not adding more resistance. In effect, you are subtracting resistance, because the significant thing that you are doing is ADDING A WIRE. By definition. if you are adding a resistor in parallel you are also giving the current and another path to go down. You may notice that the total resistance that Mr. Swarrthout came up with (3.41 Ohms) is LESS than the lowest single resistor in the circuit (R1 at 7 ohm). This is only right and proper and will ALWAYS happen in a purely parallel circuit.

[@stepbystepscience]

Yes, you are exactly right, great point, thanks for commenting. you can see a listing of all my videos at my website, www.stepbystepscience.com
